wow! arkansas to arizona!
this happens to me a lot in large stores. my friends tease me about my "mall lung", the imaginary disease i get from all the clothing fumes while shopping, but what happens is i lose all idea of where i am and how i got there. it's kind of freaky, so it helps to try to shop, even for groceries, when i am at my best. then the others inside will help out and keep me out of the "men's intimates" department.
kaika, have you ever tried using gps? this helps me a LOT! i program it before i leave my driveway and haven't gotten lost since.
